Had a look at the actual Debian os-prober (1.79) package and found
that they use /bin/sh as their shell for all their os-prober scripts.
So for Fedora and other downstream packages, someone must be going
through all the scripts and changing them to /usr/bin/sh. Switch
to the Debian variety since they're the upstream of everybody for this.
